The Basics
If you haven’t sold or bought anything major and don’t have significant investments, filing your return will be relatively simple.
- Salaried workers: Your employer should have given you your IRPF withholding certificate (Spanish income tax) at the beginning of the year. There you’ll see:
- Total gross income
- Total withholdings applied
➔ If you worked for more than one company, you’ll need a certificate from each.
- Other basic aspects you should go through:
- Union dues (box 0015)
- Professional association fees (box 0016) – only if membership is mandatory in your case.
- Donations to NGOs (box 0707) – 80% deduction for the first €150, and 35% for the remainder.
- Prize money from contests or bank referral campaigns (automatically included if the bank is Spanish). Now I’ll explain what to do if the bank is foreign, like Trade Bank , which I mentioned in a previous finance post.

Here comes the clarity. This was something that really intimidated me my first year too. I thought it was super complicated. I’ll share everything I know here, but it’s also worth noting that you can book a phone appointment with the Spanish tax agency, and they’re very helpful.
The short summary: If you rent out a property, you need to declare income and expenses.Income is the total paid by your tenants throughout the year. In my case, it’s monthly rent × 12 months.Deductible expenses are where things get interesting. truco del almendruco.

Home and rental insurance | ✅ Yes | Must be related to the rental property. |
Life insurance linked to mortgage | ❌ No | Not necessary for the rental activity. |
Community fees | ✅ Yes | Monthly homeowners association fees. |
Maintenance and repairs | ✅ Yes | Only for upkeep, not improvements (e.g., fixing a water heater). |
Property improvements | ❌ No | Not deductible (e.g., installing a new automatic awning). |
Property depreciation | ✅ Yes | 3% annually on the building's value (not the land), based on purchase price.. |
Furniture depreciation | ✅ Yes | 10% annually on the estimated value if the rental is furnished. |
